NEWPORT BEACH, California -- Sometime after this whirlwind week ends, Tre Mason is going to have a decision to make.

Mason, coming off of a 1,621-yard season, has seen his stock shoot up NFL draft boards, meaning the junior has to weigh whether or not it's best to leave early or come back for his senior season.

ESPN draft analyst Todd McShay thinks Mason's stock has risen about as high as it can go.

"There are always small things you can improve upon in your game," McShay said. "I don't think there's going to be a huge jump in terms of how he's running, his patience or his vision."

Mason, a Heisman Trophy finalist, will not be able to improve on some of what NFL teams will consider shortcomings, namely his height -- he's listed at 5-10, but is likely actually a couple of inches shorter -- and overall size.

"Running backs are tricky, because they have such a short shelf life," McShay said. "I don't know that he's a first or second-round pick. He might be a third-round pick. I don't that coming back or leaving early is going to make a big difference in that."

Mason has always talked about his NFL aspirations, although he hasn't said what his decision will be after the game.

In any case, he doesn't feel any extra pressure to perform against Florida State's defense because of the attention he's been getting or the possibility that he might be entering the draft process.

"I don't feel much pressure because I have a lot of trust in the guys that are in front of me," Mason said. "I have a lot of confidence in them getting their job done which allows me to get my job done. I don't feel too much pressure."

And he shouldn't.

After the way Mason ran against defenses like LSU, Georgia, Alabama and Missouri, NFL draft experts have plenty of reasons to like Mason, even if he plays a position that teams have waited until the late second or early third to find in recent years.

"I've been really impressed with his vision, and the way he's able to accelerate off his initial cut," McShay said. "He's running hard. ... I've been really impressed with how he's stepped up in the biggest games."
